Twintek Investment Holdings Limited (HKG:6182) shares have had a really impressive month, gaining 25% after a shaky period beforehand. The last 30 days bring the annual gain to a very sharp 46%.

Since its price has surged higher, given close to half the companies operating in Hong Kong's Construction industry have price-to-sales ratios (or "P/S") below 0.3x, you may consider Twintek Investment Holdings as a stock to potentially avoid with its 1.4x P/S ratio. Although, it's not wise to just take the P/S at face value as there may be an explanation why it's as high as it is.

How Has Twintek Investment Holdings Performed Recently?

For instance, Twintek Investment Holdings' receding revenue in recent times would have to be some food for thought. It might be that many expect the company to still outplay most other companies over the coming period, which has kept the P/S from collapsing. However, if this isn't the case, investors might get caught out paying too much for the stock.

What Are Revenue Growth Metrics Telling Us About The High P/S?

The only time you'd be truly comfortable seeing a P/S as high as Twintek Investment Holdings' is when the company's growth is on track to outshine the industry.

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 46%. This means it has also seen a slide in revenue over the longer-term as revenue is down 67% in total over the last three years. Accordingly, shareholders would have felt downbeat about the medium-term rates of revenue growth.

Weighing that medium-term revenue trajectory against the broader industry's one-year forecast for expansion of 10% shows it's an unpleasant look.

With this in mind, we find it worrying that Twintek Investment Holdings' P/S exceeds that of its industry peers. Apparently many investors in the company are way more bullish than recent times would indicate and aren't willing to let go of their stock at any price. Only the boldest would assume these prices are sustainable as a continuation of recent revenue trends is likely to weigh heavily on the share price eventually.

The Final Word

The large bounce in Twintek Investment Holdings' shares has lifted the company's P/S handsomely. It's argued the price-to-sales ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

We've established that Twintek Investment Holdings currently trades on a much higher than expected P/S since its recent revenues have been in decline over the medium-term. With a revenue decline on investors' minds, the likelihood of a souring sentiment is quite high which could send the P/S back in line with what we'd expect. Unless the the circumstances surrounding the recent medium-term improve, it wouldn't be wrong to expect a a difficult period ahead for the company's shareholders.

It's always necessary to consider the ever-present spectre of investment risk. We've identified 2 warning signs with Twintek Investment Holdings (at least 1 which makes us a bit uncomfortable), and understanding these should be part of your investment process.
